Formula Explanation of Goals Saved Above Average Calculator:
The formula for calculating GSAA is: (League Average Save% * Shots Against) - (Shots Against - Saves). This calculates the difference between expected goals against (based on league average) and actual goals against.
Detailed Explanation of Goals Saved Above Average Calculator:
GSAA provides a way to compare goaltenders while accounting for the number of shots they face. A positive GSAA indicates performance above league average, while a negative GSAA indicates below-average performance. This stat is particularly useful for comparing goaltenders who face different volumes of shots or play different amounts of time.
Importance of Goals Saved Above Average Calculator:
This stat is valuable for understanding a goaltender's performance relative to their peers. It combines elements of traditional stats like save percentage and goals against average, providing a more nuanced view of goaltender performance.
Historical Use of Goals Saved Above Average Calculator:
GSAA is a relatively modern statistic, gaining prominence in the era of advanced hockey analytics to provide context to goaltender performance.
Historical Context:
GSAA is part of the advanced analytics movement in hockey, which has gained prominence in the 21st century. It represents an attempt to more accurately quantify a goaltender's value beyond traditional stats.
Limitations of Goals Saved Above Average Calculator:
While more contextual than simple save percentage, GSAA doesn't account for the quality of shots faced or situational factors like power plays. It also relies on the league average save percentage, which can fluctuate.
Example of Goals Saved Above Average Calculator:
If a goaltender faces 1000 shots, allows 80 goals, in a league with a .910 save percentage, their GSAA would be: (0.910 * 1000) - (1000 - 920) = 10 GSAA.
Famous Examples of Goals Saved Above Average Calculator:
In recent years, goaltenders like Andrei Vasilevskiy and Connor Hellebuyck have consistently posted high GSAA numbers, indicating their elite performance relative to league average.
Frequently Asked Questions:
What is considered a good GSAA in the NHL?
A positive GSAA is considered good, as it indicates above-average performance. Elite goaltenders might have a GSAA of 20 or more over a full season, while a GSAA around 10 is very good.
How does GSAA relate to other goaltending stats?
GSAA combines elements of save percentage and shots faced. A goaltender with a high save percentage who faces many shots will typically have a higher GSAA than one with a similar save percentage facing fewer shots.
Can GSAA be used to compare goaltenders across different seasons?
Yes, but with caution. GSAA is relative to league average in a given season, so comparing across seasons with different league averages may not always be directly equivalent.
